This listing is for 9490CWDM-4MX-LC only. Use description below as a general reference.

The 9490 series of CWDM passive multiplexers (mux) and de-multiplexers (demux) offer a flexible, cost-effective solution to mux and demux up to eight fiber channels onto a shared fiber trunk. Used in conjunction with our fiber EO and OE converter cards, digital video, audio, and IP can all be carried over a shared fiber trunk. CWDM offers a cost-effective, scalable, and convenient solution for multiplexing and de-multiplexing discrete channels onto a shared fiber trunk.

The 9490CWDM mux units and companion de-mux units are available in 4 and 8-channel versions. Both 8 and 4-channel versions are available with expansion ports that allow additional passive mux/demux units to be daisy-chained on to the shared fiber trunk. The passive devices use no frame power and are fully functional regardless of frame power or communication status. Each device occupies 2 frame slots.
